VENTILATOR.

Application filed August 24, 1926.

This inventionrelatcs to an improvement in a ventilator, and more particularly in ventilator which permits the circulation of air while preventing the entry of light and which cannot be seen through.

The primary object of this invention is to provide a ventilator ofthe type specified, comprising va plurality of louvers rigidly mounted in a sash in two sets, one set on each side thereof, between which set-s of louvers a plate is located which can be raised or lowered to admit air without permitting visibility or the entry of light.

A further object of this invention is Vto provide a ventilator of this type in which the sash is made up of two frames, to which frames the louvers are rigidly secured, one set of louvers to/each frame, whereby each is complete initself before it is assembled with the other to form the finished ventilator.

Other objects of this invention will appear from aconsideration ofthe following deings which form a part thereof, and in which Fig. l is a front elevationv of a ventilator embodying this invention; y

vFig. l() is a section taken along the line 10-10 of Figure 3';

Fig. 1l is a sectional view talren along the line ll-ll of Figure 3; and

Figs. 12 and 13 are sectional plan views of the two frames whichform the completed sash, each frame being provided with its louvers rigidly secured thereto.

Referring to the drawings, the reference numeral2() is employed to designate the ventilator formingthe subjectof this invention,

.which comprises a rectangular-,sash 2lv on Serial No. 131,184.

separated from each other, both horizontally and vertically, to provide transverse passages 23, and a central compartment 24. The louvers are divided into two sets, onev on cach side of the compartment Within the compartment 24 is located a'plate 25 provided with a plurality of slots 26 separated by imperforate portions 27, so arranged that when the plate. is in the lower position, as shown in Figure 3, the portions 27 block the passages 23, sothat the ventilator is closed, but when the plate is raised as shown in Figure 2 the slots 26 coincide with thc passages 23 so that vthe ventilator is open.

The sash 2l is formed from a pair of frames 28 and 29. The frame 28 comprises bars 30 having an outwardly facing rectangular channel 31 provided with a lateral flange 32 extending at right angles thereto, which form the. top and sides of the frame, and a Z-shaped bar 33, which forms the bottom. The frame 29 comprises bars 34, at the top and both sides, having an outwardly bracing channel 35 and a Z-shaped bar 36 at the bottom, whichis the counterpart of the bar 33. The bars forming each frame are rigidly welded together, preferably at the ycorners along the lines 37. It is obvious, however, that other means for uniting the meinybers of the frame could be employed, if dethe bars 30 land 34 along the inner walls of the channels 3l, and 35.V

After the frames 28, 29 have been made and the louvers 22 rigidly secured in place,

the two frames which are shown in Figures l2 and 13, are yassembled to form thesash 2l by welding the flanges 32 to the bars 34, as shown in Figure l0. This results in providing van inwardly facing channel 43 between the outwardly facing channels 3l and 35.

The flanges 32 are of sufficient width to separate the sets of louvers to provide the compartment 2% in which the slotted plate is free to reciprocate.

The lower edge of the plate 25 is cut away, as shown in Figure 7, to provide a rectangular recess 50 at the center and rectangular tabs 5l, 52 at each end. In these tabs 5l, 52 are formed inclined. slots 53, by

means of which the plate 25 will be raisedl onlower'ed, asv desired. VA U-shapedstrip 54 receives theV tabs `5l, 52 'and carries rollers suitably .mounted upon rivets or pins 56 between the sides of the strip 54, which ententhe slots 53. The strip 54 bears against the flanges 57 of the bars 33 and'36, so thatit cannot move vertically, while through a slot 58 in'l the-vertical wall' of the bar 36 extends a lhandlie- 59 carried-by the strip 54. 0hH vio'usly by'm'ea'ns'of the handle'59 the strip 54can "be reciprocated, and' as a result by reason of'theinterengagement ofthe slots 53'and' rollers' 55, the' plate 25"will'A be* raised er loweredwhc'n the vstrip 54is 'reciprocat'ed hifoving the strip' 54toA theleft, asshown th'atthe ventilator cannot be seen `through in" any' position ofthe plate 25'.

The' bottom of the ventilator is closedby means of a ,channel plate' 60,'which is suitably's'ecured by lscrews 6l or otherwise tothe plates 33, 36.l Mounted upon the plate 60, adjacent each end are bumpers 62, with which the strip 54 will rcontact as it reaches its limit of movement. In order to'prevent. the' entry of flies, mosquitos or other insects suitable screening 63 may be secured to one face ofthe plate'25. It will b'e noted that any chance for lighter vision through the ventilator at the joinder of theslirts 41 of thelotivers with the bars 30 or 34'is prevented `by the' plate 25 at. all times. Y

AThe ventilator.embodying this 'invention is niade'and assembled as follows: The frames 28, 29 are first formed 4and then the louvers 22 kare rigidly ysecured in place, being suitably spaced from eachother to provide the passages 23.' Theframcs 28 and 29 are then united to provide'inwardly facing Lchannels 43, into which the tongues 42 of the louvers extend, 'the strips 40 ofthe upperlouvers extendingv into' the upper channel '43,' as shown particularly in Figures 2 and 3.

In the meantime the strip 54`is fixed upon the plate 25 by securing the rollers in their position throughthe slots 53. Theplate 25 and the strip 54 are then inserted in the compartment 24 between the'sets of louvers' 22 anl"th`e'hahdle `59 isfixedto the' strip 54 through the slot 58.-4 The handle 59 functions'not onlyas a handle, but also as a temporary means for-holding Kthe plate 25 and strip 54 in'the proper position inth'e Ventila- The channel bar 6() is then rigidly se- 'cured in place 'supplementing theaction of the handle 591my preventing thellow-eiing ol the strip 54. Referring particularly to Figure-x4, it will be noted Vthat the strip 54 is prevented from descending'by means of the barGO-and isplevenfted from ascending by means of the 'flanges 57. The ventilator' now coiuplete and ready to installed wherever it is desired.

It will be noted that' the skirts 4lof each pulir of -louvers22 extendfbelow the'ed'ges of ne pas ge 23, so' that' under no conditions is it 'possiblelto seethro'itigh theventilator. ivloreover, by reason ofth'efol'ni of the skirts 4l it. is impossiblefordirect raysoflight to pass throughthepassages. At thesafn'ie time, however, when` theplate25'is raised, the air can travelfreel th'roughthe kpassages 23, 'and thlus providethe'desired ventilation.

The -form of ventilator herein particularly shown and described is intended tol be used in a door in 'place of `oneof theupper"panels,

thus eliminating the' necessity of employing f transo'ius j )reviously foiindneces'sury in'order tol 'provide ventilation. The dimensions of the ventilator form nopart of this invention, l

vention as set foift inthe following' claims.

Havingv thus set 'forth my inventi'ongwhat I claim as new and foi" which I desire `proteetion'by 'Letters `Patent isz; Y ,y l
